AIPMT PRELIMS 2005 Physics Angular Resolution MCQ Question
Type: MCQ-numerical-Medium-Class 12
The angular resolution of a 10 cm diameter telescope at a wavelength of 5000 Å is of the order of:
A
106 rad
B
10⁻⁴ rad
C
10⁴ rad
D
10⁻⁶ rad
Correct Answer
Option D
Detailed Explanation
The angular resolution θ is given by θ = 1.22 λ/D, where λ is the wavelength and D is the diameter of the telescope. Substituting the given values, θ ≈ 10⁻⁴ rad.
